'Testicular pain, also known as scrotal pain', occurs when part or all of either one or both testicles hurt. Pain in the scrotum is also often included. Testicular pain may be of sudden onset or of long duration. Causes range from non serious muscular skeletal problems to emergency conditions such as Fournier gangrene and testicular torsion. The diagnostic approach involves making sure no serious conditions are present. Diagnosis may be supported by ultrasound, urine tests, and blood tests. Pain management is typically given with definitive management depending on the underlying cause. Testicular pain is when part or all of either one or both testicles hurt. Pain of the scrotum is often included. It may be either acute, subacute or chronic depending on its duration. Chronic scrotal pain (pain for greater than 3 months) may occur due to a number of underlying conditions. It occurs in 15-19% of men post vasectomy, due to infections such as epididymitis, prostatitis, and orchitis, as well as varicocele, hydrocele, spermatocele, polyarteritis nodosa, testicular torsion, previous surgery and trauma. In 25% of cases the cause is never determined. The pain can persist for a long and indefinite period of time following the vasectomy, in which case it is termed post-vasectomy pain syndrome (PVPS). List of the causes of genital pain The differential diagnosis of testicular pain is broad and involves conditions from benign to life-threatening. The most common causes of pain in children presenting to the emergency room are testicular torsion (16%), torsion of a testicular appendage (46%), and epididymitis (35%). In adults, the most common cause is epididymitis. Testicular torsion usually presents with an acute onset of diffuse testicular pain and tenderness of less than 6 hrs of duration. There is often an absent or decreased cremasteric reflex, the testicle is elevated, and often is horizontal. It occurs annually in about 1 in 4,000 males before 25 years of age, is most frequent among adolescents (65% of cases presenting between 12 and 18 years of age), and is rare after 35 years of age.
